Here at Lilies Water Gardens, we have created our own name for a category of very special plants and some of these pond plants belong in several different categories. All are very adaptable and can be grown in a wide diversity of different conditions ranging from shallow margins through to boggy conditions up to a water depth of 45cm. One thing that should be noted though, is that all species and their cultivars have a varied maximum water depth in which they prefer to be grown in.
Deep water marginal plants are by far the most dramatic of all of our pond plants not only for their height, but also for their different textures and outstanding array of colours and some of the most popular Marginal plants of them all are, Sagittaria and Pontaderia species and their cultivars. The reason why we put these plants into more than one category is simply because they are ‘True Marginal’s’ and are therefore,’ Terrestrial’ meaning they can adapt to deep water, and will even grow up to 60cm above the waterline in times of drought. If you want to attract Dragonflies and Amphibians to your pond, then these plants are definitely a must.
There does seem to be little understanding of Marginal plants needs and they are quite often sadly, overlooked when research on their individual requirements is most needed. For instance, when digging a pond it is essential that the right condition is met and observed for each marginal plant before digging has even commenced. Unfortunately, I have noted that even some of the most informative gardening books are giving out incorrect information on some of these plants and it is therefore no surprise, that first time water gardener often digs their Marginal shelves far too deep or neglects to include them at all in their pond design. However, all is not lost as we have a category on our website called “Deep Water Marginal Pond Plants” that should help to solve any teething problems and will give you an informative list of Marginals and their preferred depths.
I hope you enjoy browsing through this category and perhaps choose some of these plants for your own pond to grace your shallow or deep marginal shelves or even the bottom of your pond. However, please remember to always check the water depth of each individual plant species or cultivars and also remember that the water depth is calculated from the bottom (silt or clay level) up to the water’s surface in natural ponds, and from the top of planting baskets, or planting bags up to the water’s surface in manmade, concrete, preformed or lined ponds.
